how Jumbo jets maintain their Center of gravity with freshwater and sewage needs on board

Question

So i worked on a ship and i know we had various tanks that could be filled and emptied to modify our CoG

in an airplane that could be extremely dangerous and could have several thousand kilo’s of sewage after a long flight how do they maintain such a critical factor for flight?

EDIT:
I understand that flying is different from floating i was merely using it as an example of a system i knew and how it worked

Answer 1

The amount of freshwater and sewage on board a commercial airliner is minimal compared to the mass of the jet fuel, which at tens of thousands of liters per flight can weigh tens of thousands of kilos, making up to a quarter of the plane’s takeoff weight. The trim of the aircraft is maintained in part by actively pumping fuel between various tanks, which have plentiful anti-slosh baffles built in.
